I have a generic AMD system.
Been working fine.
Then one day, no power !
Turned out the power supply AND the hard drive were dead.
Bought new ones and now it won't fire up.
I have tried the graphics card, memory and CPU in adifferent machine and they are fine.
I took the motherboard back to my reseller who tested it and it went fine ?
The machine powers up. beeps and then nothing. It just sits there. Nothing on screen.
If you take out any components (i.e. memory) you get the appropiate number of beeps to indicate that it knows they are missing.
